GRAPHOSCOPE.

Specification of Letters Patent.

Patented Oct. 27, 1908.

Application filed November 25, 1907. Serial No. 403,760.

To all whom it may concern:

Be it known that I, ARTHUR A. FELIX, a citizen of the United States, residing in the city, county, and State of New York, have invented certain new and useful Improvements in Graphoscopes, of which the following is a full, clear, and exact specification.

My invention relates to graphoscopes and has for its object to produce an instrument of this nature superior to those now in use, in that my graphoscope is constructed in such a manner so that it maybe telescoped or folded together when not in use. This feature, dispensing with the awkwardness of the instrument (when not in use) considerably decreases the amount of space required for storing and shipping purposes and at the same time the telescoplc arrangement of my device acts as a protection to the lens when the apparatus is not in use.

Moreover, my device may be used in the usual manner by holding the device up to the eye and thus viewing the object through the lens or the device may be placed upon a table, in which event, the hand piece will act as a supporting means to the device.

Figure 1 illustrates a perspective view of my graphoscope embodying my invention. Fig. 2 is a sectional view taken through the center of Fig. 1. Fig. 3 is another sectional view, showing the device in its closed position.

Similar numerals indicate like parts in the drawings.

My improved graphoscope consists of the parts hereinafter described. I provide a casing 1, preferably oblong in shape and open at one of its shorter sides, into which the upright 2, to which the lens 3, is secured, is made to slide, being held in place by a band or tape 5, fastened both to the lower portion of the upright and to the interior back portion of the casing.

Opposite the open end of the casing 1, I provide a slot or clamp 6, for holding the object 7, to be viewed through the lens 3, as shown in Figs. 2 and 3.

The operation of my device is as follows: Assuming that my graphoscope is in its closed position, as shown in Fig. 3 of the drawings and it is desired to use same, the

following steps will place it in operative position. The instrument is taken into the hand and the projecting portion of the handpiece or support 4, is drawn out of the casing 1, the hand-piece being pivotally fastened to the upright 2, the latter is likewise drawn out of the casing at the same time. These two parts are then turned to an upright position, or at right angles with the casing. Then the hand-piece 4, is given a downward turn, thus holding the upright in place. The object to be viewed may now be placed in the clamp 6, and the apparatus is ready for use, as shown in Fig. 1. When the device has been sufliciently used it may be brought back to its original position by simply reversing the steps.

The device may be made of any suitable material and shape and while I preferably construct my apparatus out of cardboard I do not intend to limit myself to any particular material.

It is obvious that instead of tape I may employ other equivalet connecti .g Inca between the casing 1, and the upright 2, or other means than. the eyelet shown. to Coilnect the latter to the hand-piece 4, or that I may use another suitable holding means for holding the object to be viewed, than the clamp shown in the drawings aid modifications may be made in the cozzstructio illustrated without departing from the spirit of my invention, but

What I claim and desire to secure by Letters Patent is:

In a graphoscope, the combination of a lens, a folding lens support, a pocket-case, containing a receptacle for the folded lens support and lens, a band connecting the lens support and case together and adapted to hold the lens support in a vertical position at right angles to the said case and means on said case for holding a picture at the proper focus from the lens in its operative position.

In testimony whereof, I have hereunto set my hand in the presence of two subscribing witnesses.
